关于混凝土现场施工中质量控制是用混凝土强度均方差δ还是用离差系数C_v作为混凝土现场施工质量控制指标的问题,长期以来国内外一直有争论.这个问题对混凝土质量控制和配合比设计关系极大.我国自六十年代起一直采用离差系数C_v作为质量控制指标,认为在同一控制条件下,
The quality control of concrete on-site construction is the use of concrete strength variance δ or dispersion coefficient C_v as the site construction quality control indicators of the problem has long been controversial at home and abroad.This issue of concrete quality control and mix design Large.China has been using the coefficient of dispersion C_v as a quality control indicator since the 1960s, that under the same control conditions,
